Naturium Quadruple Hyaluronic Acid Serum 5% Jumbo is a water-based facial serum formulated with a blend of four types of hyaluronic acid to deliver multi-depth hydration. The 5% concentration supports surface moisture retention and deeper skin plumping without heaviness. This fragrance-free, 2-ounce jumbo size offers extended daily use for those seeking consistent moisture support.

The serum combines sodium hyaluronate, hydrolyzed hyaluronic acid, sodium acetylated hyaluronate, and hyaluronic acid to target different layers of the skin. This layered approach helps improve skin’s ability to hold water, contributing to a smoother, more supple appearance over time. The lightweight, gel-like texture absorbs quickly and leaves no sticky residue, making it suitable for layering under moisturizers, sunscreens, or makeup.

Formulated without added fragrances, essential oils, parabens, sulfates, or dyes, this serum is well-tolerated by many skin types including normal, dry, combination, and sensitive skin. It can be incorporated into morning or evening routines, applied after cleansing and before thicker creams or oils. Regular use may help reduce the look of fine dehydration lines and support overall skin resilience through sustained moisture replenishment.

The product undergoes dermatological testing and is designed for those who prefer minimal, science-backed ingredients. Typical usage involves applying a few drops to damp skin and gently pressing into the face and neck. The jumbo bottle provides a practical option for users who go through hydrating serums quickly or wish to keep a larger quantity on hand for full-face and neck application. As with any new skincare item, a patch test is recommended to confirm individual compatibility.
